7280R3A Modular Series Switch - Quick Look

Arista 7280R3A Series Introduction

The 7280R3A Modular Series are purpose built 100G and 400G systems built for the highest performance environments, and to meet the needs of the largest scale data centers and service providers. They deliver scalable L2 and L3 resources, high bandwidth encryption and high density with advanced features for network monitoring, precision timing and network virtualization to deliver scalable and deterministic network performance while simplifying designs and reducing Opex.

The modular 7280R3A system provides 14.4 Tbps of packet processing in an extremely compact and power efficient 4RU form factor providing flexibility to deploy a range of interface types including 25G SFP, 100G QSFP and 400G OSFP / QSFP-DD. For maximum flexibility a choice of three levels of scale and functionality are available; Standard (R3A), Encryption (R3AM) and Large Scale plus Encryption (R3AK).

The 7280R3A’s capabilities address the requirements for modern networking and rich multi-media content delivery requiring a lossless forwarding solution in a compact and energy efficient form factor, offering rich functionality for traditional data centre, virtualized/overlay networking and wide area networking along with deep packet buffers, large routing tables and industry leading switching capacity.

All Arista 7280R3A Series support FlexRoute™ engines for Internet scale routing and Accelerated sFlow for granular telemetry. Arista TunnelSec strong encryption and Algorithmic ACLs for flexible and scalable access control and policy based forwarding are available on the Arista 7280R3AK series.

7280R3A Advantages

• Standards-based high density 100G and 400G switch ideal for future proof designs and high bandwidth needs such as in Internet Exchanges, High Performance Storage or Content Delivery Networks (CDNs)
• Intelligent deep buffers in a fixed form factor makes an ideal spine switch where lossless performance and in-cast problems are expected such as in data analytics and IP storage
• Directly connected 50G, 100G and 200G attached storage systems, requiring high performance and predictable latency
• Comprehensive, wire-speed, cloud data center virtualization and carrier routing with EVPN-VXLAN, MPLS and Segment Routing
• Line rate TunnelSec encryption for strong layer 2 and layer 3 security
• Hardware assisted IEEE 1588 enables accurate timing solutions across Ethernet based networks without costly investment in separate timing networks
• Streaming network state for advanced analytics with CloudVision
• Unique monitoring and provisioning features – LANZ, DANZ, AEM, ZTP, eAPI
• Comprehensive L2 and L3 feature set for open multi-vendor networks with no proprietary lock-in
• Accelerated sFlow and IPFIX for network forensics
• Scalable forwarding table resources allow deployment flexibility in both large L2 and L3 environments for emerging network workloads
• Programmable packet processor for advanced features and flexible profiles enabling different use cases including peering and DCI
• NEBS compliance and DC power for service provider environments
• Flexible support for 10G, 25G, 40G, 50G, 100G, 200G and 400G with wide selection of optics and cables including OSFP, QSFP-DD and QSFP form factors

Arista EOS

Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency.
